Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Effects of Chemicals: Overview

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Chemical Synapses

Chemical Synapses

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Background:

Dynamic multilevel systems are emerging platforms for studying thermodynamic systems.
Previous research has not explored fully communicated three-level systems.

Purpose of the Study:

To investigate unprecedented fully communicated three-level dynamic systems.
To develop methods for selectively activating and controlling chemical exchanges within these systems.

Main Methods:

Screening of reaction conditions to selectively activate thiol/dithioacetal, thiol/thioester, and thiol/disulfide exchanges.
Sequential application of activation conditions to construct multilayer dynamic systems.
Analysis of information transmission between different exchange pools.

Main Results:

Selective activation of individual or paired thiol-based exchanges was achieved.
Multilayer dynamic systems were successfully constructed.
Directional information transmission between layers was demonstrated.
The ability to modify relationships between layers through network operations was established.

Conclusions:

This work presents the first synthetic dynamic chemical system with tunable layer relationships.
The developed systems offer a new platform for studying information flow in complex chemical networks.
These findings open avenues for designing advanced responsive materials and molecular devices.
